Heidi Kassenborg, the director of the dairy and food inspection division of the Minnesota Department of Agriculture said, "We can't be certain that meat from other stores is not involved, since the brand ... was likely sold at other Sam's Club locations."

Therefore, Sam's Club has voluntarily issued the recall across stores nationwide.

A statement released by Sam's Club said that the recalled patties have expiration date of February 12, 2008 listed on the packages, and were coded UPC 0002874907056 Item 700141.
